摘要
通过添加聚合硫酸铁(PSFe)降低水体中的活性磷,对水体中磷浓度、藻类生物量、碱性磷酸酶活性(APA)、类胡萝卜素/叶绿素a(Car/Chl.a)等指标随时间变化的情况进行了研究.结果表明,添加PSFe后,活性磷(RSP)迅速下降,藻类生物量和Car/Chl.a在短期内并没有显著变化.总碱性磷酸酶活性(TAPA)则随着RSP的下降而迅速升高,溶解性碱性磷酸酶活性(DAPA)上升幅度较小.结果表明,PSFe是一种优良高效的除磷剂,水体中TAPA、DAPA对RSP变化敏感,能在一定程度上指示水体中磷的变化.
The effects of polymeric ferric sulphate (PSFe) on the reactive soluble phosphorus (RSP), phytoplankton biomass, alkaline phosphorus activity (APA) and carotenoid chlorophyll a ratio (Car/Chl.a) were investigated. After adding PSFe, RSP decreased rapidly, while phytoplankton biomass and Car/Chl.a remained relatively constant in the short term. Meanwhile total alkaline phosphataseactivity (TAPA) sharply increased, and dissolved phosphorus precipitator. TAPA and DAPA were sensitive to RSP fluctuation, so they may be used as phosphorus deficiency indicators.
